1. A band-pass filter comprising:
a plurality of resonators that are electromagnetically coupled to each other,
wherein at least one of the plurality of resonators is a specific resonator to which an input signal is input from outside of the band-pass filter or that outputs an output signal to the outside,
wherein the specific resonator includes
a conductor pin,
a first surrounding conductor that surrounds the conductor pin in a radial direction,
a dielectric that is positioned between the conductor pin and the first surrounding conductor,
a second surrounding conductor that surrounds the dielectric in an axial direction of the conductor pin,
an intermediate conductor that extends in a direction crossing the axial direction of the conductor pin and electrically connects the conductor pin to the first surrounding conductor or the second surrounding conductor,
a connection pin that extends in the axial direction of the conductor pin at a position spaced apart from the conductor pin, and includes a first end and a second end, and
the first end is connected to the intermediate conductor and the second end is connected to the second surrounding conductor.
